PHOTGGRAPHIC CAMERA.

SPECIFICATION forming part of Letters Patent No. 295,638, dated March 25, 1884.

Application tiled November 2, 1883. (No model.)

To all whom t may concern:

Be it known that II, AUGUsr HERZOG, or Guttenberg, Hudson county, and State of New Jersey, have invented certain new and useful Improvements in Photographic Cameras, of which the following is a specication.

This invention has reference to an improved portable photographic camera for amateurs, which can be folded up into narrow space and used with great convenience; and the invention consists of a supporting base-frame that is applied to a tripod and provided with horizontal and axially-turning guide-rods, along which the lens-carrying frame is adjusted and secured by suitable sleeves and set-screws. The guide-rods arejointed bya hinge-connection, the shorter portions being applied to the base-frame. The rear frame of the camera is hinged to the lbase-frame, and provided with grooved transverse guide-strips for the plateholder and ground glass. A pivoted plunger of the hinged rear frame is guided in a ixed socket of the base-frame, and secured byasetscrew, so as to adjust the rear frame to any desired inclination. Vhen the bellows-shaped part of the camera and the lens-carrying frame is folded up against the rear frame, the outer longer part of the jointed guide-rods is swung up into vertical position and retained by suitable retaining devices of the lens-carrying frame, whereby the camera can be stowed away into a smaller compass.

In the accompanying drawings, Figure l represents a side elevation of my improved photographic camera, shown as folded up and stowed away in its portable case. Fig. 2 is a side elevation of the same, partly in section, shown drawn out for use. Fig. 3 is an end view of the camera as folded up, and Fig. 4. is a side elevation of the camera, partly in section, showing the rear frame adjusted to a backward inclination. l

Similar letters of reference indicate corresponding parts.

A in the drawings represents the base of my improved photographic camera, which is applied in the usual mannerA to a tripod or other suitable support. 0n the base A is arranged a short upright standard, B, to which the rear frame, G, ofthe cameraD is hinged. rlllhe rear frame, C, is provided with grooved transverse top and bottom strips, d d, for the ground glass E and double plate holder F. The strips d d are further provided at the ends with pivoted catches d', or with other equivalent means for securing the ground glass and plate-holder against lateral displacement. For the plateholder I prefer to use the construction shown in the patent for plate-holders granted to me heretofore, No. 248,175, dated October ll, 1881. The hinged rear frame, G, is capable of adjustment to different degrees of inclination on the upright standard B by means of a rod, e, that is pivoted to a lug, e', of the bottom strip d. rllhe rod e slides in a fixed cylindrical socket, e2, of the base A, and is clamped thereto by a set-screw, e3. By this means the rear frame can be turned on its hinge-connection with the base-frame, and set to any degree of inclination required by the picture to be taken.

To the upright standard B are applied horizontal guide-rods G in such a manner that they can be readily turned on their axis. For this purpose the threaded ends of the rods G are made of a smaller diameter, and passed through holes of the standard B.

To the projecting ends of the rods G are applied clamping screw-nuts g, and washers g at one side and washers g2 at the other side of the standard B, as shown in Fig. 2. Each guide-rod G is made of two sections-a shorter one, which is applied to the standard B, and -which isabout equal in length lwith that part of the base A extending in front ofthe standard B, and of a longer section, that is centrally recessed and hinged to the outer end of the shorter section, which end is tted into the central recess of the longer section, as shown in Figs. l and 2. Ihe guide-rods G serve for guiding the lens-carrying frame H in forward or backward direction by means of bottom sleeves, h, and clamp-screws h. When it is desired to extend the camera, the longer sections of the guide-rods are thrown down into horizontal position into line with the shorter sections. rEhe guide-rods G are then turned on their axes, so that the hinge-connection of their sections is in a horizontal position, as shown in Figs. 2 and 4., whereby the longer rod-sections are prevented from swinging vertically, andform a rigid support for the lenscarrying frame. Vhen it is desired to stow away the camera in the box, the lens-carrying frame H and the bellows-shaped part ofthe IOO camera are folded. up against the rear frame, l C, after which the guide-rods are turned on their axes until the hingejointsot' the rod-sections permit the swinging up of the longer sections into upright position, as shown in Figs. l and 3. In this position the longer rod-sections are retained by bent and perforated horizontal spring-catches i or other suitable means, that engage the ends of the rods G and hold them in upright position, as shown in Figs. l and In this manner the camera takes up a small space, and can be conveniently stowed away in a box in which it is carried.

The advantages ot' my improved camera are that the adjustment of the camera is accomplished in front of the rear frame7 and not back ofthe. same, as heretofore, and that the solid backwardl y-extendin g base, having guideways for the movable rear frame ol' the camera, is entirely done away with. The operator may thereby get olose to the ground focusing-glass without being ineonvenieneed by the backwardly-extending base that presses against his chest. Another advantage is that the appa ratus takes up but little room when folded up, and supports the camera7 plate-holder, and ground glass in a very compact and handy state.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. rIhe combination of a supporting basei'rame having forward-extending guide-rods, a rear frame hinged to the base-frame, means lor adjusting the rear frame to the properinclination on the base-frame, an extensible camera, a lens-carrying frame, and means whereby the lens-carrying frame can be adjusted on the guide-rods, substantially as set forth.

2, In a photographic camera, the combina tion of a supporting biiise-frame, a rear frame having means i'or supporting the ground glass and plate-holder, said rear frame being hinged to the base-frame, a camera in i'ront ofthe rear frame, a plunger pivoted to the rear fran'le, a fixed cylindrical socket oi" the baseframe for guiding the plunger, and a clamping'screw i'or fastening the plunger to the socket, sub stantialiy as specified.

In a photographie camera, the combina` tion oi'a supporting base-trame, a rear 'frame having means for supporting the ground glass and plateholder, horizontal guiderods made of two hinged sections, the shorter oi' which is applied to tliebaseirame, an extensible camera having lens-carrying frame, and means whereby the lens-carrying frame is secured to the guide-rods, substantially as and i'or the pur pose set forth.

4t. In a photographic camera, the combination ot' a supporting base-frame, a rear frame having means for supporting the platel1older and ground glass, horizontal guidesections iliade ot' two hinged sections, the shorter of which is applied to the basename, an extensible camera having a movable lenscarrying frame, means for guiding the latter on the guide-rods, and means l'or retaining the longer rod-section in upright position on the lenscarrying frame, substantially as set iorth.

In testimony that I claim the foregoing as my invention I have signed my naine in presence ot' two subscribing witnesses.
